Abstract
An apparatus and method for sizing and separating particles of generally low-density materials includes a stand, a frame movably suspended on the stand by a plurality of suspension assemblies, and an elongated screen box mounted on the frame. The screen box receives material to be processed at an input end and includes openings at an output end for discharging processed material. The frame and screen box are disposed at an incline relative to a horizontal surface on which the stand rests, so that material travels downwardly in the screen box toward the output openings. A vibrator motor is mounted on the frame input end. The arrangement of the motor and suspensions results in imposition of a combination generally circular planar motion to the frame and screen box at the input end and a generally oblong linear reciprocating motion at the central portion and the output end of the apparatus.
